through the ripening 14, into the casing. The rotation of the crank 34,andv the members driven thereby, is continued until the dishes areclean, whereupon the "cover 6, is again swung back and the frame 39, and

tray 39f, are again raised above the water leve lg'and rinsed with hotwater, which is sprayed from the pipes as and 49. The clean dishes maythen be removed from the tray and other dishes substituted therefor, orthe tray containing the clean dishes may be'removed, and another trayused for the next dishes to be cleaned, while the dishes previouslycleaned are drying. When it is desired to clean the device, thereceptacle is filled with hot water, the drain pipe 55,

opened, and the pump operated as is usual until the water is completelydischarged, and

the spray pipes 48 and 49, are then used to give the side, intermediateand bottom walls a final rinse.

It is obvious fromthe construction described that many important detailsof construction may be varied without departing .from the principles ofour invention. We

therefore do' not purpose limiting the patent granted on thisapplication otherwise than necess itatedby the prior art.

\Ve claim as our invention:

1. In a device of the class described a receptacle comprising bottom,side and end walls, relatively short intermediate walls secured to saidbottom wall and spaced away from said side walls to afford a passage ateach side or" the same, a casing connected to said receptacle andprovided with openings which communicate with said passages at the sidesof the receptacle, means affording va passage between the intermediatewalls, .which communicates with the receptacle ceptacle, a casingconnected with said I'eceptacle comprising a rigid and. a hinged sectionof constant radius for approximately 270 degrees 'of-"its circumference,

and a pump journaled in said casing-,{adaptmeans affording a passagebetween thelower' portion of said casing and the receptacle,

ed to draw the liquid content of the receptacle through the passagesaitorded by the intermediate walls and return the same un-' der pressurethrough the passage afforded between the casing and the receptacle.

3. In a device ofthe class described a re-' ceptacle,means affording apassage on each side of the same, a casing secured to 'cne end of thereceptacle provided with open ings in its ends adapted topermit theinlet of a liquid content from said passages,

means affording apassa ge between the cas-l ing, and the receptacle at apoint slightly below the center of the receptacle, androtatable meanswithin the casing adapted to draw the liquid into the casing from saidside passages and force the same therefrom under pressure through thepassage between the casing and the receptacle.

4. In a device of the class described a receptacle comprising bottom,side and end walls, relatively intermediate walls'sec'ured to saidbottom walls and spaced from said side walls to afford a passage at eachside of the receptacle,"and a pump adapted to draw a portion of theliquid content from the receptacle through the side passages and thenforce the same back into the receptacle bet-ween said intermediatewalls.

In testimony whereof we have here-unto subscribed our names in thepresence of two subscribing witnesses.
